螺旋叶片带板齿式轴流脱粒与分离装置试验台功耗的试验研究

Study on Power Consumption about the Axial Flow Threshing and Separating Installation with Helical Blade Plate

利用自行研制的螺旋叶片带板齿式轴流脱粒与分离装置试验台,以喂入量、滚筒线速度和导板导角作为试验因素,采用正交旋转组合设计的试验方法,对水稻脱粒与分离过程中的功耗进行了研究,得到以下结论:随着喂入量的增加,功耗增大;当滚筒线速度过大或过小,功耗均增大;功耗随着导板导角的增大而减少。

Using the self-developed axial flow threshing and separation with helical blade plate experimental bench, with the method of the orthogonal rotational combination design, volume of feeding and line speed of rolling-drum and guide board and angle as experimental factor, to test the power consumption in the rice threshing separation process and the experiment. Results show： power consumption enlarge as volume of feeding increasing; power consumption will enlarge if line speed of rolling become oversize or undersize; power consumption decrease as guide board and angle increasing.
